side AB = 3.2 cm (i) Draw a circle with radius 3.2 cm. (ii) Take a point A on its circumference. (iii) With the same radius of 3.2cm, taking A as centre, cut the circle at B. (iv) From B, with the same radius, cut the circle at C and so on until you obtain 6 point..

Construction - 14 - To construct a right angled D ABC when hypotenuse AC = 4 cm and hypotenuse and one acute angle are given (1) Draw a straight line AC = 4cm. (2) Taking OC as diameter, draw a semi circle on AC. (3) At A, construct meeting the semicircle at B. Join BC. (4) Then D ABC is ..

Question: Prove that an equilateral triangle can be constructed on any given line segment. Answer: Let AB be a given line segment. According to Euclid's postulate 1, a circle can be drawn with any centre and any radius. Taking A as the centre and AB as radius, draw a ..

Concurrency of the angle bisectors of a triangle - Draw a triangle ABC. Draw its angle bisectors. The angle bisectors pass through a point. Recall the procedure to draw angle bisectors: With B as centre and with a convenient radius draw an arc of a circle to cut AB and AC at X and Y. With..

(This is a circle with centre (3,-2) and radius 6..

In ABC in the figure above, the bisectors of the three angles meet at I. I is the Incentre. With I as centre and IM as radius, a circle drawn to touch the sides, is called the Incircle. In a triangle, the perpendicular bisectors of the three sides meet at a point called the Circumcentre. ..

The locus of points equidistant from two fixed points is the perpendicular bisector of the segment joining them. Locus of a point equidistant from a given point in a plane is a circle. The locus of points equidistant from two given parallel lines is a line parallel to the two lines and midway ..

Introduction - Every geometric figure has a shape and a size. Two circles of different radii have the same shape but their sizes are different. But if we draw two circles of the same radius both the shape and size will be the same. Such figures with the same shape and size are c..

Question: Construct a D ABC such that BC=6cm, AB=6cm and the median AD=4cm. Answer: Steps of Construction: Step 1: Draw a rough sketch and mark the given measurements. Step 2: Draw BC = 6cm. Step 3: Bisect BC at D. Step 4: With B as centre and radius equal to 6cm, draw an a..
